Storage Temperature: within 1 month (-20~ 50°C), within 3 months (-20~ 40°C), within 3 months (-20~ 20°C)
A 26650, i.e. considerable fatter than 18650, but the same length. Capacity is higher than 18650, but not as much as the battery volume increase. Depending on where I check the specifications the maximum discharge current varies.
The battery works well up to 7A, higher current do look strange and 30A do not work (I redid the curves at 10A and above, they looked different, but did not improve).
Conclusion
The battery works fine at "lower" currents, but it cannot deliver the current that is printed on it or anything near that. When using 7A or lower the battery looks good, but capacity is a bit low (but higher than rated).
Well I am looking for a good 26650 with good capacity + high current discharge capability and I bump into this AWT battery. Looks like it is a good battery, but depends on the price too.
Thank you once more for a thorough battery test. It shows us that a being great in a specific (battery)size not per se means that you are top of your class in all other sizes. My champion still is the Keeppower IMR26650 4200mAh (Black).
Edit. In case that my remarks are perceived as being negative: don’t focus on a particular brand of batteries or chargers. Make up your mind about the size of the batteries you want to put in your light and then go browsing through the extensive research-data HKJ has given to us. I will not buy a single battery or charger without first consulting HKJ’s data.
OK, I forgot about the 26350’s but they are doing just fine :person_facepalming:
